Aradia used to be something of an archaeologist, and her hive was surrounded by dig site trenches of her own doing. She was present when a meteor from traveled back and crashed nearby, revealing the presence of the reckoning and carrying with it and a deceased alternate Aradiabot, both severely damaged. She sent Cal on to for repairs and spent some time exploring the Frog Temple.
She is able to hear the voices of the dead, which she has heard since she was young. The voices have been getting louder ever since she was in a fatal accident ; the magnified voices led her to descend into fatalistic resignation about everything and left her only concerned in dealing with the impending apocalypse of which the voices warned.
Aradia's Fetch Modus, the Ouija, is uncontrolled by her. She says that it's "not up to [her] to decide" what she gets from the sylladex, and it is "up to the spirits." She goes on to say how they are sometimes cooperative with what she wants, but are commonly cryptic in their choosing. This is shown when the spirits select the letters that translate to "Bing" in English to pick the computer.
Aradia lost most of her interest in ordinary activities after her death, and now appears to be constantly bored. She reacts ambivalently to most everything. The only thing she seems to find pleasure in is breaking things.
Before her death, she seems to have been happier and more enthusiastic, complimenting Tavros on his sense of fun while playing Flarp. It also appears that she enjoyed the movies of Troll Indiana Jones, which likely influenced her decision to be an archeologist and to use the whipkind strife specibus. She has since stopped caring about both archeology and role playing, along with essentially all of her former interests.
Her ability to hear the dead, including her ancestors, may have also contributed to her archeological exploits. They are what led her to the Frog Temple Ruins in the first place, shortly before her death.
Aradia is obsessed with temporal inevitability, and her motivations usually involve doing things solely because she knows they have to happen. It is this attitude which often allows time loops to form in the first place, and easily makes her a pawn of Sgrub and whatever beings influence the timeline, including , who likely had her killed for this purpose. After entering the Soulbot made by Equius, she appears to have regained some emotions. These seem to be violently extreme, although it is possible she's simply forgotten how to handle emotions, having spent so much time without them. For example, while as a ghost, she once told Vriska that she was "0k" with her own death, but shortly after she entered the soulbot, she sought out Vriska and beat her to death for revenge. It is also implied that the Soulbot has enhanced her strength and psychic abilities. Now that she has had time to get used to the body, she appears to still be fatalistic and jaded, but now she is simply a lot more violent and confrontational on top of that, though she does acknowledge certain trolls (such as Karkat) as friends. This change is probably brought on by the violent tendencies from the blue blood in soulbot. Karkat has called her a "tin can psychopath," and suggests that she would be closer to her original personality if she were to be properly brought back to life.
This is more or less true once Aradia achieved God-tier and is, officially, very much alive and intends to stay that way. She is enthusiastic and kind even when talking about depressing things. She is convinced that there is no reason to grieve, and thinks that things are going to turn out okay. Considering her knowledge of the time stream, it is likely that she knows some hopeful things later in the timeline, as she knew Sollux would see her again, but he would be blind. Aradia has abandoned her typing quirk now, even though she used it prior to her death. This change might be related to her claim that she feels "truly alive for the first time."
